I read some articles online and found fun facts about my personality seen from blood type. These describe me very well:
AB Blood Type : Talented, Calm, Rational
People with blood type AB are hard to categorize because they have both A and B characteristics in them. They are both introverted and extroverted, and they are often viewed as having multiple personalities because they shift from one personality to another. While they enjoy hanging with friends, they need time alone to think to themselves. Sometime they think something too deep and overthink thoughts. They seem very unforgiving as they are precise and tough to themselves and those around them. At the same time, people with blood type AB are very sensitive and very cautious. Koreans usually categorize people with AB as either a genius or an idiot.
Best traits: cool, controlled, empathetic
Worst traits: aloof, unforgiving
Type AB: The Humanist
Type-AB people are an unpredictable, distant lot, but tend to use their heads over their hearts. They are good with money. Type AB’s are the split personalities of the blood groups. They are considerate of other people’s feelings and deal with them with care and caution. On the other hand, though, they are strict with themselves and those close to them. They, therefore, seem to have two personalities: one for those “outside,” and another for people on the “inside.” They often become sentimental, and they tend to think too deeply about things. AB Types have a lot of friends, but they need time to be alone and think things through, as well. They can be both outgoing and shy, confident and timid. While responsible, too much responsibility will cause a problem. They are trustworthy and like to help others. Type AB personalities can be sensitive, considerate, careful, and efficient. They can also be strict, moody, easily offended, critical, and standoffish.
